Answer:
C. A mass of air that is similar in temperature and humidity
Explanation:
An "air mass" refers to a big volume of air that is characterized by having similar or uniform "temperature" and "humidity"<em> (moisture).</em> They come from different source regions, thus they are classified accordingly.
The<em> "cold air masses"</em> come from the <u>polar area</u>s while the<em> "warm air masses"</em> come from the<u> tropical areas.</u> An air mass may cause a storm, for example, when an air mass moves to a new region and confronts another air mass there with a<em> different humidity and temperature</em>.
Answer: B. Show that light was composed of different colored rays
Explanation:
In the eighteenth century Isaac Newton found out that when a beam of light from the Sun, passes trhough a prism is decomposed in many different colors. He named this phenomenom as dispersion of light.
This phenomenom occurs when a beam of white light (which is compound of many wavelengths or "colors") is refracted (the different rays of light are diverted depending on their wavelengths) in some medium, leaving their constituent colors separated.
